Tsistispas v. Dimitrov seems very compelling to me. Both seem to be rather renewed in form and motivation, playing some of their best tennis at the same time. Some will be compelled, as usual, like
@mrzz, by the battle of the one-handers. I'll give the slight edge to the Greek for youth, height, and, what ought to be ambition.
I don't give Rublev a snowball's chance v. Novak, even if he is still sick. A bucketful of options + experience + savvy, vs. a one-and-a-half-trick pony. I do expect some histrionics, most likely from the Russian's side of the court. But if it goes 3, on both sides.
